ADJUSTABLE ROTARY-BRUSH MEGHAINIBM.`

Application mea January VT'o all whom it may concern.

Be itknown that I, EUGENE BERTONE,

c a citizen of the United States, residing at -Stevenso'n, in the county -of Baltimore,

State of'Maryland, have invented certain new and useful Improvements in Adjustable Rotary-Brush Mechanisms, of which the following is a specification.

This invention relates to scrubbing machines, and especially to an adjustable rotar brush mechanism.

. gne object of this invention is to provide a brush-actuating mechanismv that is illJ sertable into a combustion chamber or cylinder of an internal combustion engine,

through the spark-plug-openings, after the' spark-plugs are removed, and 1s angularly' adjustable while so inserted, thereby ena- -bling the brush to ,be moved into contact with various parts of the combustion chamber and the parts contained therein, while rotating, for removing deposits of carbon from such chamber and other parts.

Other objects and important features are pointed out or limplied in the following details of description, in connection with the accompanyngdrawngs in which- Fig. 1 is a side view, partly in, section,

the brush omitted, the parts being adjusted for insertion into the spark-plug-openings.

Fig. 2 is a longitudinal sectional view, the parts beingA adjusted to the angular positionl for being operated to rotate the brush and to shift the brush about the axis of the primary driving shaft, by manually turning the. device about said axis. Fig. 3 is an assembly detail view of the jointedcasing and parts' therein, as viewed from the lower side of Fig. 1.

InI each of these-views, parts are broken out, showing that thebroken partsmay be 'of any proper and convenient length. The

device, -accordin to the cross-section here shown, can easi y be inserted in a seveneighths (7/8 inch diameter) spark-plug-opening; but larger or smaller sizes may be found preferable. I

Referring to the drawings in detail, in which similar reference characters correspond to similar arts throu hout the several views; but rst explaining that such drawin shewv only one of many forms embraced 1n the principles and inventive ideas, this 'f ormf will now be described as follows: Two cylindrical casings 5 and 6, lare j hinged togetherat 7 by means of a hingebers, with this device.

mechanism of any appropriate form. These elements are herein referred to as the hinged casing. Suitable bearings vided in the hinged casing, and a primary or driving shaft 11 is journalled in the bearings` 10, while aesecondary or driven shaft 12 is journalled in the bearing l9. Bevel gear-wheelsl 13 and 14 are carried on the shafts 11 and 12, res ectively, in such relation to `the hinge-jolnt 7 that they are in mesh with one another when the hinged casing is adjusted angularly as shown in Fi 2, that is, when `the casings 5 and 6 ho d their shafts 12 and 11 with their axes at ri ht angles to one another. For adjusting t e hinged casing, a preferably iexible and springy wire 15, of steel for instance, is pivotally connectedat 16 to the casing 5 and extends thence through guides 17 and 18 on a tubular extension 19 ofthe casing 6. This extension is of considerably smaller diameterthan the casin A and ermits the device to be tlected in all directions while inserted in the` sparkplug-opening. A loop or otherl form of handle 20 may be grasped' for pullin the wire 15, to bring the device to the a justment shown in Fig. 2; or for pushing the wire, to bring the device to the adjustment shown in Fig. 1. A set screw 21 or other securing means may be providedto hold the wire 15 ,in its different adjustments.

The brush 22 is provided with a threaded socket which fits on the threaded outer end 5 and 6,

9 and 10 are proof-the shaft 12, and any appropriate form of brush may be thus attac ed 'to and detached from theshaft'12. In ractice, 'a steel wire brush is found very e eetive for removing carbon,'from combustion cham- The vshaft 11 may be rotated by any appropriate means, for instance, by a flexible extension 23T-.which may be connected to any form of lmotor or rotor which is suitable for the purpose of rotating this shaft at the desired speed. The iexible shaft 23 is secured (by any appropriate means) in a sleeve 24' Y I in which the rigid shaft 11 isalso secured by a pin extending through it and through the sleeve' 24, and this sleeve may also constitute a thrust bearing, acting' in conjunction with a journal-bearing 25 which is secured in the tubular extension 19. A flexible tube 26 may enclose the flexible shaft 23, and a clamp maybe employed to secure the ilexible tube on the tubular extension 19. The

i guide 18l may be formed integrally with the l main part of this clamp.

Any appropriate lubricating material may be inserted in the casing 6 and extension 19, by, any appropriate means, through nory mally plugged or closed openings (not shown), and theshaft 12 and its bearing are easily accessible for lubricating.

n The device must be adjusted to thefsition shown in Fig. 1, for the purpose of inserting it in a sparkplugopening, and after q it is inserted far enough for the hinge-joint vto be entirely inside the combustion g chamber, the lwire 15 may be pulled-v v foradjusting the device angularly, as in Fig. 2, and when so adjusted, the rotation of the shaft 11 will cause the shaft 12 to rotate; so, if the brush is now on the` shaft V12, it can be moved against al1 sides of the combustion chamber for dislodgin the carbon therefrom. The dislodged car n can then be blown or oth` -erwis'e ejected from the combustion chamber.

-What I claim as my invention, and desire to protect by a patent, is:

1. The combination.- of a pair o fbevel gear-wheels, shafts on which said gear-- wheels are carried respectively,v bearingsy in .which Said shafts are mounted to rotate,

means on .one of the shafts for securing a brush or the like thereon, two members lhinged to one another and carryingy said bearings and adjustable for alternately moving these shafts into axial alinement and into suchposition that their axes are at an` angle to one another and the gear-wheels are in mesh with one another,-and a. manipuj lative adjusting member'for eifectig these adustmen for the urpoee specifi The ombinatiolliof a pair` of bevel gear-wheels, a shaft for rotating one of these gear-wheels, a shaft carrying thev other gear- I wheel and rotatable thereby and adapted to carry a brush or-the like, bearings for these shafts, two casings hinged to one another and having the bearings for the respective shafts secured therein, and a manipulative adjusting member pivted to vone of said casings and operable to move these casings on the hinge thereof in such relation that the shafts are thereby moved from axial alinement to axial angularity and the gearwheels are moved from a non-meshing to a.

meshing relation with one another.v

3. The structure defined by claim 2, said casings being cylindrical and of a size to be inserted in a spark-plug-opening, said hinged to one another on a pivot -positioned to space said gear-wheels when in axial alinement, said casings 4carrying the bearings of the Arespective shafts therein, said casings being provided with any suitable' means to swing them on their hinge-connection and tol hold their shafts at different angular adjustments with respect-to one another.-
